Storage Redundancy (1 / 16):

Your company's infrastructure on Azure uses unmanaged disks for their applications. They initially chose Geo-Redundant Storage (GRS) for its perceived benefits of increased protection. However, they are starting to experience consistency issues and are considering a switch to a different redundancy option.

What could be causing the consistency issues your company is experiencing with their current storage setup?
What storage redundancy option should your company consider switching to for their unmanaged disks, and why?
What are the potential trade-offs your company might face with this new redundancy option compared to GRS?

Answer:

The consistency issues your company is experiencing could be due to the use of GRS with unmanaged disks. This setup is not recommended as it may lead to potential issues with consistency due to the asynchronous nature of GRS.
Your company should consider switching to Locally Redundant Storage (LRS) for their unmanaged disks. LRS is recommended because it avoids the potential consistency issues seen with GRS when used with unmanaged disks.
The trade-off with LRS is that data is not replicated in a secondary, geographically distant region as it is with GRS. Therefore, in the event of a major disaster that affects the entire primary region, your company might lose their data.
